Title: Pattern recognition system
Inventor: USUI MASAKO
IPC: G06K9/68
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To reduce labor for setting a threshold value, to take a suitable threshold value for minimizing the number of candidates to be sent to the next layer even concerning any arbitrary input pattern, and to enable high-speed matching processing by setting the threshold value for each input pattern based on the distribution of all similarity provided by comparative collation and the area, where a correct answer pattern exists, for each estimated feature. SOLUTION: A feature extracting part 103 extracts a feature expressing the form of a character from a sent character pattern. While using plural features, a matching part 104 compares the input pattern with a standard pattern stored in a recognition dictionary 106. When one feature is completely collated and compared, on each layer of the matching part 104, the threshold value is set at a threshold value setting part 105, candidates are narrowed from this threshold value, and only the suited standard pattern is sent to the next layer. At the matching part 104, this layer matching processing is successively performed and the standard pattern closest to the input pattern is finally selected and outputted as the correct answer pattern by a result output part 107.

Title: Inspection of magneto-optical disc
Inventor: ADACHI NOBUYUKI
IPC: G01M11/00
Filed: 1988-11-11
Abstract: PURPOSE:To achieve a higher detection accuracy and a shorter inspection time in the detection of a defect by obtaining reproduction signals simultaneously when a recording layer of a magneto-optical disc is in recording or in erasion to determine a difference signal between both the signals. CONSTITUTION:First, a direction of magnetizing a recording layer of a photomagnetic disc is adjusted to a direction opposite to the direction of erasion to be made ready for recording and under such a condition, three light beams are made to scan over the disc. A first signal reproduction is accomplished by the preceding first light beam, a signal erasion by the subsequent second light beam and furthermore, a second signal reproduction by the third light beam following the second light beam. Thereafter, a first reproduction signal obtained by the first signal reproduction is delayed by a period during which the first signal reproduction precedes the second signal reproduction and a difference signal is determined between the first reproduction signal thus delayed and the second reproduction signal obtained by the second signal reproduction. Thus, based on the difference signal, a defect of said magneto-optical disc is inspected.

Title: Insulated gate bipolar transistor
Inventor: HARADA MANA
IPC: H01L29/68
Filed: 1987-11-11
Abstract: PURPOSE:To avoid the occurrence of latch-up state effectively by a method wherein a trench is formed in a 1st region and a conductive layer which is electrically connected to the 1st region and a 1st electrode is provided on the inner surface of the trench. CONSTITUTION:A trench 14 is formed at the approximately central part of a P-type well region 3. An emitter electrode 7 made of metal such as aluminum is extended onto the inner surface of the trench 14 so as to connect the P-type well region 3 in the trench 14 to an N<+>type emitter region 4 electrically. By applying a metal wiring into the deep part of the P-type well region 3 like this, the vertical resistance RB1 of the central part of the P-type well region 3 can be lowered. By lowering the vertical resistance RB1, the ratio of a hole current Ih1 flowing vertically to a hole current Ih2 flowing immediately below the N<+>type emitter region 4 can be increased in the distribution of the hole current Ih. If the hole current Ih2 flowing immediately below the N<+>type emitter region 4 is reduced, the creation of a potential difference in the boundary between the P-type well region 3 and the N<+>type emitter region 4 is suppressed so that the transition to latch-up state of the IGBT can be effectively avoided.
